Lichuan 4 axis stepper need help-

Well, I think it follows the state diagram up to the point of operation
 

But for sure it isn't perfect. I have noticed multiple homing components around even if I don't use it myself.
Can you add support for PV (Profile Velocity) while you are at it? I made a quick fix for that.
PV is suitable for spindle mode.

You should be able to transition states manually, in halshow for example, using controlword and check statusword.
Maybe that can give a clue to why it seems so grumpy.
